FLANGE-LINING MACHINE.

Application filed. January 5, 1917, Serial No. 140,667. Renewed June 5 1922.- S'erial N0. 565 896.-

To all who m may concern;

1 it known that l, JOHN M. Ho'rHnnsALL, .-.'ti.i:en of the United States, residing in 1. in the county of Kings and State of New York, have invented a new and useful improvement in Plunge-Lining Ma'- chines. of which the following is a specitica lion.

'liis invention relates in general to the of securing flanged can ends to flanged bodies with interitolded seam and '1' its object broadly the provision'oi' a l or process for accomplishing this 'ation to produce an economical and perhermetic seal. The inventionalso nplates an improved apparatus for 'plishing this result.

Prior to my invention it has been generally the custom to deposit a flange lining compound on the ot the can end byz-novin z the flange beneath nozzle from i the coiizpouiid is ejected. It the in to be closed are or other than circular -ro;- -;--;c(.'tioi'i the application of the compound in this manner has necessitated coinpiica" 2d machinery for it the nozzle best-aiiormry .an irregular movement must be 1 flange to cause the complete flange indei' the nozzle. or it the tla-nfre be 'y a like irregular movement must 71'! the nozzle. Either. i'eqiiiires involved or complicated machinery and eon siderahle mechanical changes it different shapes or sizes of can ends are to be lined.

A hig 'hly important object t this-inven- 'on is the provision of an apparatus for pplying' lining material to one of the 1 es to he intert'olded. which may he ta-(lily adjusted "for cans of differing dimenions and of differing shapes.

Another iortant object or the invention is the orovismn of a mechanism or apparatus adapted to permit the use or :i greatly hea compound than usual; which is nevertheless pro .ded in ii thin film which KIloV understood from the following description when considered in connection with the ac- 2--2 of Fig, 1 and looking in the direction indicated by the arrowsa, ca; v

I Fig. 6 is a section taken substantiallyon the line (i-6 and looking in thedircction of the arrows e in Fig. 2; and

Fig". 7 is a plan View of somuolji oi the mechanism as is shown in Fig. Referring; to the drawings, referencecharactor l indicates an electric motor mounted upon a main base 2 of the apparatus. The motor 1 is coutrolledhy a rheostat 3 and a switch 4, the rheostat 3 and the switch 4- being supported by aplate '5 carried upon suitable upright nieml'iers 6 and 7, the latter being in turn carried upon the base. 2. The motor 1 delivers power through the medium of a number of spur gears 8 and Sto e worm 10, which worm 10 has abcaring'in the worm case 11 and cover 11. the worm case 11 being also secured upon the baseQ. The worm 10 acts directly-upon it Worm wheel .12 which actuates main driving shaft. 13 through a friction transmission, which friction transmission consists of pressure plates- 14 and 15 mounted upon and to turn with the shaft 13 and spring 16 acting; directly upon the plate 15 to hold the parts in clutching relation. 3

The driving shaft 13 has a bearing in the worm-case 11 at one end and in a bracket 18 at the other and a (entrails-caring in the bracket 17, brackets 17 and 18 being secured upon the base 2.

' A pulley 19 is mounted upon the shaft 13 between the brackets 17 and lS and a threepart belt 20 is trained over this pulley and receives motion from it. The three-part belt is also trained over a pulley 21. which is between tne roller shaft r? a loose pulley, and is mounted in bearings 23 and 24. These bearings are supported by rods 25 extending out from the bearings 27 and 28. On the drawing the arrangement at one side only is completely shown, it being understood that the arrangement at the opposite side is a substantial duplicate. This arrangement permits of the ready adjustment of the tightness of the three-part belt. The members or parts of this belt are spaced apart as indicated in Figs. 1, 2 and 7 for a purpose which will be later described.

Underneath the upper limb of the belt and between the power pulley 19 and the idle pulley 21, a plate 29 is positioned and supported by cross-members 30 and 31, the cross-member 30 being fastened upon the top of the bearing brackets 17 and 18, and the cross-member 31 upon the top of the hearing bracket 27 and 23. The belt. in moving onto this support receives can bodies to be treated and the support causes the belt to have a smooth and level operative travel. The cans 32 are delivered on to the belt. from a chute or table 33 traveling in the direction of the arrow 34 and they leave the belt on to slats 35 forming a second chute or table.

The belt forms a conveyor for moving the cans beneath a roller numbered l3 on the drawing, which roller, as will be pres ently described, causes him or coating of flange lining compound to be applied to the flange 58 of the can body.

This roller rec ives continuous motion from the shaft 13 and to this end I have provided a bevel 3'? upon the shaft 13 which gear meshes with a similar bevel gear 38 secured on the lower end of an inclined shaft 39. This shaft is supported in two brackets 40 and ll, the bracket 40 having a bearing upon the shaft 13 itself and forming in turn bearing for the lower end of the shaft 39. Bracket ll is movable along the shaft 39 and has a bearing in turn upon a shaft 42 which. carries a pinion l l in mesh with a-pinion movable with but slidable upon the shaft 39. The shaft 432 also carries a pinion i-5 meshing with a pinion 46 upon the roller shaft 47, the shafts 42 and 47 having; bearings in ahead 49 1noun"ed move vertically upon two rods 50 ant. 51 supported from the base 2. Then thus arranged the head 49 may be moved vertically without destroying or altering the operative connection and the main driving); shaft 13. Vertical movement is given. to the head 49. to adjust the apparatus to cans of different height and this is the only adjustment needed to adapt the machine to operate upon cans oi"; different sizes and ditl erent shapes. This vertical adjustment is impart d to the head by a screw 52 carrying at its top a hand wheel 53. It will be manifest that the roller receives a continued rotation in synchronism with the movement of the conveyor and that the motion of the two is in the same direction. The roller in its movement travels adjacent the tank which is divided into two compartments,--one 56 for the compound and the other 57 for the heating fluid, as water. This tank is mounted upon the head 49 by a rod and water in the compartment 57 is heated electrically by heating coils 60 controlled from a switch 61 upon the plate 5. The tank is placed closely adjacent the roller as, the side being curved as shown in Fig. 5. The lower part of this sideis cut away at (i l to permit the compound to contact with the roller as it turns. A scraper 62 is fastened at the bottom of the tank and this scraper operates to determine the depth of film or coating applied to the roller as it turns past the opening 64. This opening is advantageous ly arranged near the line of application of the film to the flange 58 as is indicated in Fig. o. A drip cup 58 is provided upon the tank and adapted to supply a limiter quantity of water to the compartment 56 as the compound dries out by evaporation, and water may be supplied to the compartment 57 through a pipe 59.

In the operation of the apparatus, the cans are carried continously under the roller. which acts as a feeder receiving first a film or coating of compound and then bringing this film, or coating into contact with the flange 58 of the cans, depositing from this contact sufficient coating upon the flange to form the desire-Ll seam. The can passes between the roller and the conveyor and the relative movement between the two causes the roller to roll over the flange with substantially a pure rolling action which does not permit the flange to scrape the material from the roller.

The chute parts 35 enter between the belt parts 20 and are of substantially the same thickness so that the cans slide easily from the conveyor out of the apparatus.

Since the material is thus mechanically applied as a film and not run from a nozzle, a heavier compound can be used t-llitll has heretofore been considered possible. My invention contemplates the provision of a thicker or less fluid compound in a thinner film. This permits the can ends to be immediately applied and the compound, while still plastic to be forced tl'iroughout the seam.

it will be manifest from the foregoing that there is substantially no waste or comrcceivnw a film or coatin Z3 the conveyor, means for adjusting said frame, and mechanism ior actuating said conveyer and turning said roll so that their opposing suritaces move in the same direction. I
